Problems solved by technology

In the prior art, if it is necessary to form hot-bent glass with different bending radii, different molds need to be made accordingly, resulting in high mold costs
In addition, the glass hot bending molds used in the prior art are usually made of cast iron, stainless steel and other materials. The hot bending molds need to withstand the attack and erosion of softened glass during use. Repeated use will easily lead to deterioration of its surface quality, thus affecting the surface quality. quality

Embodiment 1

[0017] The chemical composition of the D-type graphite cast iron of the present embodiment is as follows: 3.0wt% C, 0.9wt% Si, 1.2wt% Mn, 2.0wt% Cu, 0.22wt% Ti, 0.05wt% Cr, 0.03wt% Al, 0.02wt% of P, 0.01wt% of S, the balance is Fe and unavoidable impurities. Put the raw material of cast iron into the medium frequency induction furnace to melt according to the ratio, and make the molten iron superheated, measure the temperature through the thermocouple and adjust the temperature of the molten iron to 1500-1550°C; use Si-Fe inoculant to inoculate the molten iron, the particle size of the inoculant 3-5mm, and the addition amount is 0.3wt% of molten iron. In actual operation, it should be ensured that the inoculant can be fully and evenly dissolved into the molten metal in the ladle. After the operation is completed, the slag can be removed and then poured. for 10.0 hours.

Embodiment 2

[0019] The chemical composition of the D-type graphite cast iron of the present embodiment is as follows: 3.2wt% of C, 0.65wt% of Si, 1.0wt% of Mn, 1.8wt% of Cu, 0.12wt% of Ti, 0.08 of Cr, 0.05 of Al , 0.02wt% of P, 0.01wt% of S, and the balance is Fe and unavoidable impurities. Put the raw material of cast iron into the medium frequency induction furnace to melt according to the ratio, and make the molten iron superheated, measure the temperature through the thermocouple and adjust the temperature of the molten iron to 1500-1550°C; use Si-Fe inoculant to inoculate the molten iron, the particle size of the inoculant 3-5mm, and the addition amount is 0.3wt% of molten iron. In actual operation, it should be ensured that the inoculant can be fully and evenly dissolved into the molten metal in the ladle. After the operation is completed, the slag can be removed and then poured. for 10.0 hours.

Abstract

The invention belongs to the technical field of mould manufacturing and relates to an adjustable glass hot-bending mould. The adjustable glass hot-bending mould comprises a rectangular mould base and a bendable metal plate, the rectangular mould is formed by splicing of C-shaped steel, four borders of the base are provided with a plurality of screw rods, the bendable metal plate is provided with a plurality of holes all around, and the holes and the screw rods are in one-to-one position correspondence. The bendable metal plate is mounted on the screw rods through the holes, and each screw rod is provided with two nuts above and below the bendable metal plate respectively. The adjustable glass hot-bending mould has advantages that plate glass can be processed into a required curved shape by nut position adjustment without mould increase, and processing and forming of glass different in curve degrees can be realized by adoption of the same mould. In addition, the adjustable glass hot-bending mould has advantages of high surface quality, high forming quality and long service life.

Description

technical field [0001] The invention relates to the technical field of mold manufacturing, more specifically, the invention relates to an adjustable glass hot-bending mold. Background technique [0002] As a transparent material, glass is widely used in construction, automobile and other industries. However, the commonly used flat glass has a single style, and it is difficult to meet the application requirements in many occasions. With the progress of the industrial level and the improvement of people's living standards, the use of hot-bending glass in the fields of construction and automobiles is also increasing. Architectural hot bending glass is mainly used for interior and exterior decoration of buildings, lighting roofs, sightseeing elevators, arched corridors, etc.; in the automotive field, it is mainly used as glass side windows, front windows or roof windows. In the prior art, hot-bending glass is formed by heating and softening flat glass in a mold, and then anneal...
